LLMDet (large variant)

LLMDet model was proposed in LLMDet: Learning Strong Open-Vocabulary Object Detectors under the Supervision of Large Language Models by Shenghao Fu, Qize Yang, Qijie Mo, Junkai Yan, Xihan Wei, Jingke Meng, Xiaohua Xie, Wei-Shi Zheng.

LLMDet improves upon the MM Grounding DINO and Grounding DINO by co-training the model with a large language model.

You can find all the LLMDet checkpoints under the LLMDet collection. Note that these checkpoints are inference only -- they do not include LLM which was used for training. The inference is identical to that of MM Grounding DINO.

Intended uses

You can use the raw model for zero-shot object detection.

Here's how to use the model for zero-shot object detection:

import torch
from transformers import AutoModelForZeroShotObjectDetection, AutoProcessor
from transformers.image_utils import load_image


# Prepare processor and model
model_id = "iSEE-Laboratory/llmdet_large"
device = "cuda" if torch.cuda.is_available() else "cpu"
processor = AutoProcessor.from_pretrained(model_id)
model = AutoModelForZeroShotObjectDetection.from_pretrained(model_id).to(device)

# Prepare inputs
image_url = "http://images.cocodataset.org/val2017/000000039769.jpg"
image = load_image(image_url)
text_labels = [["a cat", "a remote control"]]
inputs = processor(images=image, text=text_labels, return_tensors="pt").to(device)

# Run inference
with torch.no_grad():
    outputs = model(**inputs)

# Postprocess outputs
results = processor.post_process_grounded_object_detection(
    outputs,
    threshold=0.4,
    target_sizes=[(image.height, image.width)]
)
